Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a car seat massage headrest. Background Technology

[0002] With the development of the automotive industry, various human-machine interface functions of car seats, including comfort and safety, are being developed. These include features such as seat heating, seat ventilation, voice control, environmentally friendly materials, and rear entertainment screens. These primarily aim to increase the functionality, comfort, and use of high-end materials; the more features, the higher the price. To help relax the neck and shoulders during long drives, some seats have added massage functions to the headrests, allowing users to massage and relax their neck and shoulders at any time.

[0003] Modern car seat headrests not only need to meet passenger comfort but also multi-functionality. In this context, electric massage headrests have emerged. However, because the electric massage mechanism inside the headrest requires electricity to operate, and because the headrest also has a height-adjustable function, the electric massage mechanism cannot meet the need for quick removal when the headrest is installed or removed from the seat body due to the fixed wiring connection.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a car seat massage headrest, in order to achieve a more practical purpose. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that addresses the inconvenience of assembling and disassembling a headrest with electric massage function from a seat.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car seat massage headrest, including a headrest portion disposed at one end of the car seat, a massage mechanism disposed within the headrest portion, a sleeve one fixedly connected inside the car seat, a positioning rod inserted into the sleeve one, one end of the positioning rod penetrating through the headrest portion, a locking assembly disposed between the sleeve one and the positioning rod, a sleeve two disposed inside the car seat, an outer support rod slidably connected within the sleeve two, an inner wire rod slidably connected within the outer support rod, one end of the outer support rod penetrating through the headrest portion, a contact electrical connection assembly disposed between the inner wire rod and the sleeve two, and a magnetic fixing assembly disposed between the inner wire rod and the contact electrical connection assembly.

[0007] In a preferred embodiment, the headrest portion includes a headrest frame surrounded by a sponge filling layer, the outer surface of which is covered with a skin layer.

[0008] In a preferred embodiment, the massage mechanism includes a motor fixedly connected to the headrest frame. The output shaft of the motor passes through the headrest frame and is fixedly connected to a connecting plate. Multiple massage heads are fixedly connected to the connecting plate. A breathable mesh layer is sewn onto the skin layer, and the massage heads are located on one side of the breathable mesh layer.

[0009] In a preferred embodiment, the locking assembly includes a positioning box, which is fixedly connected to the outer surface of one end of the sleeve. A retainer and a pressure plate are slidably connected inside the positioning box. The retainer and the pressure plate are fixedly connected and are located on both sides of the positioning rod. A spring telescopic rod is fixedly connected between the retainer and the positioning box. The outer surface of the positioning rod is provided with multiple slots for the retainer to engage.

[0010] In a preferred embodiment, one end of both the external support rod and the positioning rod passes through the skin layer and is fixedly connected to the headrest frame.

[0011] In a preferred embodiment, the contact power connection assembly includes a base, which is fixedly connected to the inner wall of the sleeve two. A power supply base one is fixedly connected to the base. A pair of conductive posts are provided on the top of the power supply base one. A power supply base two is fixedly connected to the bottom of the inner wire rod. A pair of conductive springs are provided at the bottom of the power supply base two. The conductive springs are in contact with the conductive posts. The conductive springs are connected to the motor through wires. The conductive posts are connected to the vehicle power supply through wires.

[0012] In a preferred embodiment, the magnetic fixing assembly includes an electromagnet fixedly connected to the base, and a magnetic block is magnetically connected to the electromagnet, the magnetic block being fixedly connected to the bottom end of the inner rod.

[0013] The technical effects and advantages of this utility model are as follows: This car seat massage headrest, through the insertion and cooperation of the positioning rod and the sleeve, allows the headrest to be height-adjusted based on the car seat. With the locking component's press-type locking method, the positioning rod and the sleeve can be quickly locked and unlocked, making it convenient to adjust the height of the car seat.

[0014] This car seat massage headrest uses a motor to rotate the massage heads on the connecting plate. The massage heads can rotate and massage the shoulder and neck area through the breathable mesh layer, thereby relieving the user's shoulder and neck pressure and fulfilling the function of electric massage for the headrest.

[0015] This car seat massage headrest, after the magnetic fixing component is energized and fixes the inner cable rod in position, the contact connection component can then abut against the electrical connection to provide power to the motor inside the headrest. Through the sliding cooperation of the outer support rod and the inner cable rod, the height-adjustable headrest can drive the outer support rod to slide adaptively on the inner cable rod. The outer support rod and the inner cable rod, while meeting the height adjustment requirements of the headrest, ensure a stable magnetic connection of the contact connection component. Similarly, by releasing the magnetic connection of the contact connection component, the headrest can be easily and quickly removed for maintenance, improving the disassembly and assembly speed of the electric function headrest.

[0020] See also 1- Figure 8 This utility model provides a car seat massage headrest, including a headrest part disposed at one end of the car seat 1. The headrest part includes a headrest frame 2, and the headrest frame 2 is surrounded by a sponge filling layer 3. The outer surface of the sponge filling layer 3 is covered with a skin layer 4.

[0021] The headrest frame 2 provides support for the structure of the headrest, the sponge filling layer 3 increases the softness of the headrest, the sponge filling layer 3 uses breathable memory foam, and the covering layer 4 can be covered with leather.

[0022] In this embodiment: a massage mechanism is provided inside the headrest, the massage mechanism includes a motor 5, the motor 5 is fixedly connected to the headrest frame 2, the output shaft of the motor 5 passes through the headrest frame 2 and is fixedly connected to a connecting plate 6, a plurality of massage heads 7 are fixedly connected to the connecting plate 6, a breathable mesh layer 24 is sewn on the skin layer 4, and the massage heads 7 are located on one side of the breathable mesh layer 24.

[0023] Multiple massage mechanisms can be set up to be arranged around the neck and shoulder area in a reasonable manner. The model of motor 5 is ZYT-51S-8-185.

[0024] By starting the motor 5, the motor 5 can drive the multiple massage heads 7 on the connecting plate 6 to rotate. One end of the massage head 7 is rounded. When the user's shoulders and neck are pressed against the breathable mesh layer 24 of the headrest, the breathable mesh layer 24 can meet the breathability requirements of skin contact. The rotation of the massage head 7 can massage the shoulders and neck to relieve shoulder and neck pressure.

[0025] In this embodiment: a sleeve 9 is fixedly connected inside the car seat 1, a positioning rod 8 is inserted into the sleeve 9, and one end of the positioning rod 8 passes through the headrest. A locking assembly is provided between the sleeve 9 and the positioning rod 8. The locking assembly includes a positioning box 10, which is fixedly connected to the outer surface of one end of the sleeve 9. A card seat 11 and a pressure plate 12 are slidably connected inside the positioning box 10. The card seat 11 and the pressure plate 12 are fixedly connected and are located on both sides of the positioning rod 8. A spring telescopic rod 13 is fixedly connected between the card seat 11 and the positioning box 10. The outer surface of the positioning rod 8 is provided with multiple slots for the card seat 11 to engage.

[0026] The positioning box 10 is designed in an I-shape with a sliding groove inside. The fixedly connected card seat 11 and pressure plate 12 form a U-shaped structure and slide in the sliding groove. The inner side wall of the card seat 11 is provided with a protrusion that engages with the card groove. The spring telescopic rod 13 consists of a telescopic rod and a spring sleeved on the telescopic rod. The two ends of the telescopic rod are fixedly connected to the inner side of the pressure plate 12 and the inner wall of the positioning box 10, respectively.

[0027] Using the tension of the spring on the spring telescopic rod 13, the protrusion of the card seat 11 can be inserted into the card slot to lock the positioning rod 8 on the sleeve 9. When it is necessary to adjust the height of the headrest, the pressure plate 12 can be pressed. The pressure plate 12 can compress the spring telescopic rod 13, and the card seat 11 can slide in the slide groove and move away from the card slot. The positioning rod 8, which is released from its limit, can move up and down on the sleeve 9 to adjust the height of the headrest.

[0028] In this embodiment: a sleeve 2 14 is also provided inside the car seat 1, an outer support rod 15 is slidably connected inside the sleeve 2 14, an inner line rod 16 is slidably connected inside the outer support rod 15, and one end of the outer support rod 15 passes through the headrest.

[0029] The inner rod 16 can be reserved with wires to provide signals and power to the motor 5. The outer surface of the outer support rod 15 is provided with guide protrusions. The inner wall of the sleeve 14 is provided with a sliding groove that cooperates with the guide protrusions. The inner rod 16 is also provided with guide protrusions. Since the inner rod 16 is I-shaped and one end of the inner rod 16 passes through the bottom end of the outer support rod 15, the bottom end of the outer support rod 15 should be provided with a groove that allows the inner rod 16 to pass through and slide.

[0030] In this embodiment, one end of the external support rod 15 and the positioning rod 8 both pass through the skin layer 4 and are fixedly connected to the headrest frame 2.

[0031] The arrangement of the external support rod 15 and the positioning rod 8 fixed on the headrest frame 2 allows the headrest to achieve two-point support on the car seat 1.

[0032] In this embodiment: a contact power connection assembly is provided between the inner wire rod 16 and the sleeve 2 14. The contact power connection assembly includes a base 17, which is fixedly connected to the inner wall of the sleeve 2 14. A power supply base 18 is fixedly connected to the base 17. A pair of conductive posts 19 are provided on the top of the power supply base 18. A power supply base 20 is fixedly connected to the bottom of the inner wire rod 16. A pair of conductive springs 21 are provided at the bottom of the power supply base 20. The conductive springs 21 are in contact with the conductive posts 19. The conductive springs 21 are connected to the motor 5 through wires. The conductive posts 19 are connected to the vehicle power supply through wires.

[0033] Power supply socket 18 can provide insulation and fixation for conductive post 19. A pair of conductive posts 19 are divided into positive and negative poles. Power supply socket 20 can provide insulation and fixation for conductive spring 21.

[0034] In use, the outer support rod 15 with the inner wire rod 16 is slid into the sleeve 14 until the conductive spring piece 21 at one end of the inner wire rod 16 abuts against the conductive post 19. At this time, the corresponding wires on the conductive spring piece 21 and the conductive post 19 can form a circuit. The conductive spring piece 21 is connected to the motor 5 through the wire. After one end of the wire is connected to the conductive spring piece 21, the other end can pass through the inner wire rod 16. At this time, a portion of the wire needs to be reserved in the inner wire rod 16 to meet the extension and retraction of the wire when the headrest height is adjusted later. Then, the other end of the wire passes through the penetration between the outer support rod 15 and the skin layer 4, and finally is electrically connected to the motor 5 on the headrest frame 2. When the conductive post 19 is connected to the car power supply through the wire, it also needs to be connected to the PLC controller. The control circuit of the PLC controller can be implemented by those skilled in the art through simple programming. The PLC controller can operate the power and start / stop of the motor.

[0035] In this embodiment, a magnetic fixing assembly is provided between the inner wire rod 16 and the contact power connection assembly. The magnetic fixing assembly includes an electromagnet 22, which is fixedly connected to the base 17. A magnet block 23 is magnetically connected to the electromagnet 22 and is fixedly connected to the bottom end of the inner wire rod 16.

[0036] Electromagnet 22 also needs to be connected with a PLC controller for control, and the power supply is common knowledge in this field.

[0037] When the conductive spring 21 abuts against the conductive post 19, the electromagnet 22 can be controlled to generate magnetic force. The electromagnet 22 with magnetic force can attract and fix the magnet block 23, so the position of the inner rod 16 can be fixed. Therefore, the conductive spring 21 abuts against the conductive post 19 to achieve a stable magnetic connection. When the headrest is adjusted in height, since the inner rod 16 is fixed, the movement of the headrest can drive the outer support rod 15 to slide longitudinally on the inner rod 16. Therefore, the height adjustment of the headrest does not affect the stability of the power supply control of the motor 5.

[0038] When it is necessary to disassemble or assemble the headrest, the power supply to the electromagnet 22 can be disconnected, and the locking assembly can be released from fixing the positioning rod 8. After the magnet block 23 and the electromagnet 22 have no magnetic force, by providing an upward pulling force to the outer support rod 15 on the headrest, the outer support rod 15 can drive the inner wire rod 16 of the I-shaped structure to be lifted upward until the conductive spring 21 and the conductive post 19 are no longer in contact. In this way, the headrest can be easily removed, and it is also more convenient to install the headrest later.

[0039] It is worth noting that the electromagnet 22 can be opened when adjusting the height of the headrest. Since the position of the positioning rod 8 can be locked, the conductive spring 21 and the conductive post 19 can achieve effective conductive contact, which can reduce the energy consumption of the electromagnet 22.
